Platelet-derived growth factor-AA (PDGF-AA) has been used as a potent mitogen for the proliferation of oligodendrocyte progenitor cells (OPCs). Whether it plays a role in oligodendrocyte lineage differentiation of neural stem cells (NSCs) is unclear. Here we report that PDGF-AA is an instructional signal required for the differentiation of embryonic(More)
We have synthesized a 162 bp gene of human Plasmodium falciparum hybrid peptide antigen by the solid-phase phosphoramidite method with ABI 381A DNA synthesizer. The gene encodes three fragments of the relative molecules 83 kDa, 55 kDa and 35 kDa merozoite-specific proteins and two CS repeats or four peptides. The gene with the designed two cohesive ends was(More)
Large scale gene expression profiles between normal hepatocytes and hepatocellular carcinomas are detected with high throughput microarray. DNA microarrays were made by spotting PCR products of 4,096 human cDNAs onto a specially treated glass slides. The probes were prepared by labelling normal tissue mRNA and cancer tissue mRNA with Cy3-dUTP and Cy5-dUTP(More)
